Abstract
The present disclosure relates to a radio frequency identification (RFID) tag antenna. The RFID tag antenna includes: a substrate having a first surface and a second surface, a feeding structure mounting on the first surface and a rotation structure mounting on the second surface. Specifically, the feeding structure corresponds to the rotation structure for forming a resonant circuit.

A RFID tag antenna, comprising:
- a substrate, having a first surface and a second surface;
- a feeding structure, mounted on the first surface;
- and
- a rotation structure, mounted on the second surface;
- wherein the feeding structure corresponds to the rotation structure for forming a resonant circuit, one terminal of the rotation structure is coupled to a ground, and there is a gap between the rotation structure and the ground, a size of the gap being adjustable to change the resonant frequency of the rotation circuit.
